1.4Jumpers and Connectors

Connectors on the AIMB-766 motherboard link it to external devices such as hard disk drives and a keyboard. In addition, the board has a number of jumpers that are used to configure your system for your application.

The tables below list the function of each of the jumpers and connectors. Later sec- tions in this chapter give instructions on setting jumpers. Chapter 2 gives instructions for connecting external devices to your motherboard.
